An auger mining apparatus (10) includes a support frame (12) holding a tilt platform (18). A tilt mechanism displaces the tilt platform (18) at a pitch between 0 - 45 ° relative to the sup- port frame (12). A stacked, dual carriage arrangement (24, 32) is carried by the tilt platform. A bidirectional auger drive system (46) is mounted to the upper carriage (32). The dual carriages are mounted for reciprocal movement along independent paths ex- tending substintially perpendicular to one another. An auger clamp (54) mounted to the tilt platform includes a pilot member for guiding auger sections and a mechanism allowing movement on the pilot member through two separate planes; the second perpendicular to the first. The auger clamp also includes a clamp/decoupling plate and a mechanism for moving the plate in a third plane orthogonal to the first and second planes. Thus, the pilot member with the clamping/decoupling plate may also be utilized to clamp and hold an auger line in position even in steeply pitched seams.
